Why did Abhishek cry on the sets of Antara?

The on-screen sibling revelry has got extended to off-screen as well. For Zaynah Vastani, the cute Antara of Zee TV's Aap Ki Antara and lovable Raj Samaria(Abhishek in the show) who plays her brother have become inseparable in real life too. So strong is the bonding that they miss each other dearly if either of the two is missing from the sets. Recently, there was a track where Zaynah went missing and wasn't required for the shoot. The girl had fun with her family back home but poor Raj had a tough time as he kept inquiring about his dear sister Antara. Later when he realised that Antara is missing on the show, he was reduced to tears as the tiny tot assumed that the girl had disappeared for real.
Informs a source, "In the recent episodes of Aap Ki Antara, Antara was shown missing in the track and hence wasn't seen on the sets for quite some time. When her on-screen brother four and a half year old Raj asked about Zaynah he got to know from the unit members that she was on leave. However when he watched a few episodes of the show, he realised that his favourite Antara was missing. After realising this he started crying for his on-screen sister. He was inconsolable and kept saying Mujhe Antara Chahiye (I want Antara). So adamant was he that he refused to shoot until Zaynah was called on the sets."
Raj's mother confirms this and says, "It's true that Raj and Zaynah have grown extremely fond of each other. They even refuse to shoot till they are allowed to play for a while during the breaks. Zaynah even helps him with his home-work at times. When Raj couldn't comprehend that it was only in the storyline that Antara was lost, he wouldn't stop crying."
Director Sanjay Surkar adds, "We couldn't believe that both of them were actually so close to each-other. Generally Raj is very naughty and keeps the spot boys on his toes but for the past couple of days he was just not being himself. But finally when he saw Zaynah he was back in action."
